The bug started off with me entering a room except none of the NPC's bodies loaded. Just their apparel and their eyes. Then the game quickly closed. So I replayed and now it seems to randomly close whenever I enter a room, leave a room, or fast travel. No CTD errors or anything. It just randomly closes very quickly. Anyone else having this problem? It's getting incredibly annoying, like near impossible to even play the game.

Edit: I have already played the game for around 17 hours. The problem just started very recently. I have Windows 7 64bit.

Update: The 44.1Hz fix seems to have helped so far.
